Melink Corporation (513) 965-7300 8 www.melinkcorp.com ® MELINK Intelli-Hood Controls ® Intelli-Hood Features & Options Standard Features & Benefits Improved Energy Efficiency Improved Kitchen Comfort Improved Fire Safety Improved Occupant Health Improved HVAC Life The controls improve energy efficiency by reducing the exhaust and make-up fan speeds during idle periods. The controls can improve kitchen comfort by reducing the supply of hot/ humid MUA and reduce hood noise. The controls can improve fire safety by monitoring exhaust temperature and activating the fans, sounding an alarm, and/or shut down fuel to appliances. The controls can improve IAQ by monitoring CO2 levels and increasing exhaust & supply speeds if necessary. The controls extend HVAC life by reducing run tie and thus wear and tear on equipment, as well as providing softstarts for the exhaust and supply fans. On/Off Options Manual On/Off Auto On/Off Remote On/Off Remote Enable Scheduling On/Off via keypad fan button; if active this will always override any other on/off method. On/Off via temperature sensors; On temperature may be programmed. On/Off via the dry input terminals on the I/O board. Programmable setting that requires external interlock to allow fans to start. On/Off via scheduled times; may be programmed for specific days of the week. Temperature Control Options Manual Temp Span Auto Temp Span Comfort Mode Fire Safety Future Options Temperature span is manually set through the programmable menu. Auto temp span will adjust to utilize the entire temperature span and optimize energy savings. Space and supply air sensors can determine if free cooling may be utilized and will override the temperature span to increase fan speed and act as an economizer. If programmed, fans will activate in case of a temperature alarm to possibly avert a fire condition. More options currently under development. 9 Optics Control Options Optic Sensors Future Options Utilizing the optic sensors allows the system to operate more efficiently by watching for any traces of effluent. More options currently under development. Auxiliary Input Options BAS Input HVAC Input Appliance Input IAQ Sensors Remote inputs from BAS enable the controls or tell the system to turn on or off. Remote inputs from RTUs, MUA, etc. will tell the system either heating or cooling is taking place, and algorithms temporarily adjust the effective temperature span to help maximize the effectiveness of the process. Arrange for automatic fan speed adjustment based on state of cooking equipment. Remote inputs from humidity, CO, CO2 sensors or BAS system that may adjust fan speed. Auxiliary Output Options System Relay System 24VAC Output Hood 24VAC Output Programmable Form-C relay with capacity of 15A @ 230VAC 24VAC programmable output based in system menu. Can be used for alarm output, fan/equipment interlock, etc. 24VAC programmable output for each hood. Can be used for alarm output, fan/equipment interlock, etc. Additional Options Melink Corporation Remote Access Integral Datalogger Shunt-Trip Shutdown Future Options Analog or wireless feature that allows the controls system to be remotely monitored and serviced. System has on-board logger that will track fan operation for up to three weeks. Ability to ramp EFs to full speed and shut down supply fans with simple jumper setting during startup. More options currently under development.

SET-UP FAULT HOOD % Customer Service: 877-477-4190 U NSF L Listed 33x7 B Press Fan Switch ® MELINK Intelli-Hood Controls ® The hood fans turn on. Fan speed automatically varies with the heat/smoke load generated by the cooking appliances. This reduces hood noise, improves kitchen comfort, and saves energy.

This should only be used if there is noticeable smoke loss and the fans are not already running at full speed. Upon pressing this button, the bar graph will flash 100% speed and the letter “E” will be displayed with each hood designation. After the preset period of time, the fan speed will return to its previous operation mode.

Once the appliances are turned on, the fan speed will increase as the exhaust air temperature increases. This normally results in the fan speed increasing to 50-80%. E Smoke Detection Upon detection of smoke during cooking, the Optic Sensors will bypass the Temperature Sensor and increase the fan speeds to 100%. This ensures the proper removal of smoke as well as compliance with codes that require a minimum air volume and duct air velocity. Once the smoke is removed, the fan speed will decrease based on the exhaust air temperature. F Quiet Hood Operation The hoods will sound very quiet when the fans are operating at minimum speed. It may sound like the hood is turned off until the fan speed increases above 50% with the heat and/or smoke load. NOTE: Hoods sound very quiet at lower fan speeds. Melink Corporation (513) 965-7300 14 www.melinkcorp.com ® MELINK Intelli-Hood Controls ® 2 G How it Works View Current Hood Exhaust Rates During normal operation, the Keypad bar graph will indicate the percent fan speed of each hood.

First, wipe off the lenses on each end of the hood with a clean, soft cloth. Press the fan switch off and then on again to initiate automatic calibration of the Optic Sensors now that they have clean lenses. The indicator light should turn green within about five seconds to confirm calibration. IMPORTANT: Advise your hood/duct cleaner not to spray hot water or steam into the photo housings so that the Receiver and Emitter do not get wet. The photo housings should be covered to ensure protection of these devices. B Temperatures Sensors Clean the temperature sensors at least once a year or as needed by simply wiping off any grease with a clean cloth. This will ensure the sensors respond quickly to any change in exhaust air temperature.
